FIG 1. Typical imaging findings of giant ranula.
A, Axial view contrast-enhanced CT scan shows a homogenous, fluid attenuation mass centered in the submandibular space with a tail of extension anteriorly into the sublingual space (large arrow). Note the location both anterior and posterior to the submandibular gland (asterisk) due to extension into the submandibular space both posterior to the mylohyoid muscle and laterally through a congenital mylohyoid defect (small arrow).
B, Coronal view image shows cranial extension into the parapharyngeal space (asterisk), without significant mass effect on the surrounding structures. Note the relation of the submandibular component to the mylohyoid muscle (arrow). Reprinted from Harnsberger (17) with permission from the Electronic Medical Education Resource Group.
